Using Ohm's Law, how can current be calculated?

Ohm's Law states the relationship between voltage (E), current (I), and resistance (R) in an electrical circuit. It is mathematically represented with the formula I = E ÷ R. In this formula, current (I) is calculated by dividing the voltage (E) by the resistance (R). This means that as the voltage increases while resistance remains constant, the current will also increase. Conversely, if the resistance increases while the voltage is constant, the current will decrease. This fundamental principle is critical in electrical engineering and circuit analysis, allowing for the determination of current flow in various electrical systems based on known voltage and resistance values.
